Application filed August il, i919. Serial No. 316,807.

To all whom t may concern.'

Be it known that we, JAMns L. RECORD and l `HIRAM J. CAMPBELL, citizens of the United States, and residents of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful improvements in Wheels, of which the following is a specification.

rlhis invention relates to improvements in vehicle wheels of the sheet metal type.

An object of this invention is to provide a strong, durable sheet metal vehicle wheel.

Another object is to provide such a sheet metal wheel, the parts of which lend themselves to rapid quantity production.

Other objects of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the accompanying drawings, there has been disclosed a structure designed to carry out the objects of the invention, but it is to be understood that the invention is not conlined to the exact features shown, as various changes may be made within' itsy reasonable scope.

Figure l is a sectional view on the line 1 1 of Figure 2,

Figure 2 is a partial view in side elevation of an assembled wheel,

Figure 3 is a sectional view on the line 3*-3 of Figure 2.

This selected embodiment of the invention broadly includes a wheel made of two sheet metal sections preferably of pressed sheet steel. These may easily be produced by shaping with dies on a hydraulic press. As shaped each section is provided with a hub portion, spoke portions, and a rim portion. These two sections are adapted to be secured together and fastened to a hub. The hub employed is preferably a solid one, not of sheet metal, but of cast iron. The wheel may be reinforced by means of a sheet metal disk disposable between the two sections, secured to each and to the hub.

The two sections of this novel wheel are alike and each has a hub portion l, shaped to provide an annular recess so that when the two complementary sections are assembled they cooperatively form an inwardly presented annular recess. Each section is cut away and the remainder is shaped to provide a plurality of spoke portions 2. And, while the spoke portions of two complementary sections may be secured together in any suitable yway 1t 1s deemed preferable to form .each spoke portion with a flange 8 along its edge. The rim portion i of each section is shaped to form the rim of the-wheel in conjunction with its opposed complementary section. Each rim portion 4, adjacent a cutaway portion-as shown in the upper part of Figure l-is formed with'a liange 5. rlhese spoke and rim flanges provide a means whereby the two opposed sections may be secured together.

Preferably this novel wheel is reinforced, medially, by means of a disk. Such-a disk 6 is disposable intermediate two opposed sections when they are in assembled position. This flat disk is cut away similarly to the sections but is not shaped out of its plane as it passes between the assembled spoke-forming portions. When this disk member is employed, the flanges of the spoke portions and of the rim portions of the assembled sections are secured lto `opposite faces of the disk. This securing of the sectionsto the disk is preferably effected by meansof spot welding which provides a neat and practically homogeneous joint between the threesheet metal parts.

The solid hub is adapted to be received within the annular recess cooperatively presented by the hub portions l of two comple* mentary sections. lhen the disk 6 is employed, the hub 7 is preferably formed with an annular reduced portion 8 upon which the centrally apertured disk 6 is received. A bushing 9 is neXt fitted on the reduced portion 8 of the hub and is pressed against the adjacent face of the disk to retain the disk in position. The end face of the bushing is flush with the end face of the hub and against the thus-formed end face of the hub on this side and the end face of the hub on the opposite side, the two inner faces of the recessed hub portions l of the complementary sections are placed. Preferably rivets l0 are passed through the sections, bushing, disk and hub, and countersunk in the sides of the hub portions of the sections. These parts are all thereby held in relatively immovable position. I

r[he periphery of the disk 6 forms a portion of the rim of the wheel. The rim portions of the two sections are preferably is seton over the rivets.

joined kto the sides of the disk adjacent its periphery by a butt Welded joint. The riin of the Wheel is preferably formed by the two rim portions and the periphery of the disk.

rlhis invention not only provides a strong, durable Wheel but also one which can be economically produced in quantity. In rapid assembly, the countersunk rivets are passedl through the recessed hub' portion of one oit the sections and the cast iron hub The disk is then put on the reduced. portion off the hub, atter which the cast iron bushing is put on, and lastly 4the recessed hub portion of -the complementary'se'ction is positioned. VThe rivets are lthen secured by a riveting machine vand the 'Wheel is then spot Welded around the spokes and rim portions and butt Weldedl at the junction of the disk and edges of the' rim portions 0f thetwo sections.

lt is to be understood that the construction disclosed herein is illustrative, but not restrictive and that the same may be modi fied Within the meaning and claims which tolloivjv Having thus described our invention, What We claim as new, and desireV to secure by Letters Patent, is: i'

scopev of the l; ln a metallic Wheel, the combination oit a pair of opposed sheetv metal sections, each 'having a hub portion, spoke portions and a rim portion, a disk disposed intermediate the'opposed sections and adapted to be secured to both said sections; a disk-like hub hai/*ing a cylindrical, reduced portion eX- tending aXiallyfto one side and onivhich the disk is positioned against the disk-like portion of the hub, and a collar arranged on saidhub reduced portion against the opposite side or the disk to retain the .disk in position; the outer :tace of the collarand the outer lace ofsaid .hub reducedportion be Aing flush, the hub portions of the two secing of the hub.- f
